Overview

PathMatcher handles glob pattern matching for file paths

Supports gitignore-style glob patterns with:

  • Standard globs: *, **, ?, [abc], a,b
  • Recursive matching: */ matches all nested files
  • Negation: !pattern to explicitly deny

Examples:

PathMatcher.matches?("tmp/**/*", "tmp/foo/bar.rb")  # => true
PathMatcher.matches?("*.log", "debug.log")          # => true
PathMatcher.matches?("src/**/*.{rb,js}", "src/a/b.rb")  # => true

def matches?(pattern, path)
  # Remove leading ! for negation patterns (handled by caller)
  pattern = pattern.delete_prefix("!")

  # Use File.fnmatch with pathname and extglob flags
  # FNM_PATHNAME: ** matches directories recursively
  # FNM_EXTGLOB: Support {a,b} patterns
  File.fnmatch(pattern, path, File::FNM_PATHNAME | File::FNM_EXTGLOB)
